What about the little Holley 450cfm 4bbl (mec. 2nds)? Would that be 2 small? Or would the 500cfm 2bbl be a better carb?
I have 1 flowmaster allready, and I like the sound. I had not heard of the bad flow problem before is it a big problem?

as always...here we go again with "which carb is best"....my answer is "which carb tuner" is best....tuning for a heavy vehicle that is going to constantly want to tip into the secondaries due to Hg drop from high motor load driving normal

For mpg best, with any carb brand, simple enough to mount a vacuum guage on the column in the truck so you can train you size 12 boot to accelerate so that the Hg doesn't drop below 10-12Hg....and tune for the highest Hg at 70mph

depends on the weight and gears and tire size and how much intown versus hwy to decide "if" you want smaller primaries and do you want a 4V carb,

geargrinder,
I disagree with alot of the content of recent posts, suggest you study build ups for 4x4 trucks....

Gotcha! Thanks for all the input on this guys. I'm new to the hole "better milage" thing so I feel like I'm flowndering around alittle on this one. I'm more interested in around town milage without it being a dog than anything else.

Funny U should say that, I have been doing the 4x4 thing for the last 10 years. And I'm not sure how ALL the 4xers are doing it, but I know for me and my old crowd ALL THE POWER U can get, and keeping it runnin' @ ANY angle/bounce is the key. That SUCKS dead dinos like theres no tommorow I had a 454 in my last trail rig that pulled hard from 1000rpm all the way to 5500rpm, it rocked! But it got 5-6mpg
